BUGS :
- xymg, wlcc: Extra graphic during double game. dyq (ID 02185)

WIP :
- 0.135u1: Changed description to 'Xing Yun Man Guan (China, V651C)' and clone 'Wan Li Chang Cheng (V638C)' to 'Wan Li Chang Cheng (China, V638C)'. Renamed (grtwall) to (wlcc). Luca Elia implemented hopper simulation in clone Wan Li Chang Cheng (China, V638C).
- 0.127u1: Aaron Giles changed description to 'Xing Yun Man Guan (V651C)'.
- 0.126u5: Luca Elia and Wei Mingzhi fixed Xing Yun Man Guan - Game now playable. Aaron Giles changed description to 'PinYin: Xing Yun Man Guan (V651C)' (info from emuman). Added 7x 'Unknown' dipswitches.
- 10th August 2008: Luca Elia - I've taken another look at the igs_blit driver, thanks to Pierpaolo, who managed to decrypt another Mahjong game, Da Ban Cheng. I took the chance to clean up the driver, and review the protection handling in the non working games there. I managed to promoto Xing Yen Man Guan (with help from Wei Mingzhi) to a working status. The issues still open in this driver are now some lingering palette problems and, of course, proper emulation of the IGS0011 and IGS0012 ASIC's.
- 0.99u9: Added new gfx1 ($200000) rom to clone grtwall.
- 0.99u7: Changed 'The Great Wall' (grtwall) to clone 'Xing Yen Man Guan (V638C)?' of 'Xing Yen Man Guan (V651C)' - Game now playable. Changed 68000 CPU1 clock speed to 7.333333 MHz and visible area to 512x240. Added OKI6295 (7936 Hz) sound and dipswitches 'Coinage', 'Credits Per Note', 'Max Note Credits', 'Money Type', 'Demo Sounds', 'Min Credits To Start', 'Unused' and 6x 'Unknown'.
- 3rd September 2005: Luca Elia - Some more progress on the IGS blitter led to better graphics and two more games added. They are Long Hu Bang (199?) and Xing Yen Man Guan (1996) (this one still has protection issues and locks up. The clone of it that works has bad graphics, due to an undumped rom).
- 0.84u5: David Haywood added Xing Yen Man Guan (V651C) (IGS 1996).
- 0.74u2: Added 'The Great Wall' (IGS 1994).
- 0.68: Added The Great Wall (Testdriver).

TODO :
- Protection emulation instead of patching the roms.
- A few graphical bugs.
- vbowl, vbowlj: trackball support, sound is slow and low volume
- lhb: in the copyright screen the '5' in '1995' is drawn by the cpu on layer 5, but with wrong colors (since the top nibble of the affected pixels is left to 0xf) (drgnwrld is like this too, maybe hacked, or a cheap year replacement by IGS).
- dbc: in the title screen the '5' in '1995' is drawn by the cpu with wrong colors (see above comment). Also the background palette is wrong since the fade routine is called with wrong parameters, but in this case the PCB does the same.
Notes:
- In most games, keep test button pressed during boot for another test mode.

BUGS :
- dbc, lhb, lhba, xymg, wlcc: Some graphic characters missed during play. dyq (ID 02152)

WIP :
- 0.135u1: Changed igs_blit.c to igs011.c driver. IGS blitter based games update [Luca Elia]: Cleaned up driver. Changed OKI6295 clock speed to 1047619 Hz and region gfx1 to blitter and gfx2 to blitter_hi.
- 0.127u1: Pierpaolo Prazzoli changed some decryptions in IGS_Blit driver to use program roms loaded byteswapped.
- 0.102u2: Merged vbowl.c with igs_blit.c driver.
- 0.99u7: Merged chindrag.c, chmplst2.c and grtwall.c to igs_blit.c driver.
- 0.84u5: Added chmplst2.c and vbowl.c driver.
- 0.68: Added chindrag.c and grtwall.c driver.
